As the packaging bag body 1 is opened, the scratch-proof plate 3 will rotate around the bending groove 21, which can ensure that the opening of the packaging bag body 1 can be stably opened to the maximum state. The gift is put into the packaging bag body 1. A clamping elastic piece 22 is fixedly connected to the inner side of the packaging bag body 1, and a clamping block 23 is fixedly connected to the inner side of the packaging bag body 1. After the gift packaging is completed, the opening at the top of the packaging bag body 1 is closed, and the symmetric scratch-proof plates 3 are pushed to approach each other, so that the clamping elastic piece 22 approaches the clamping block 23. When the clamping elastic piece 22 gradually inserts into the clamping block 23, the inclined surface of the clamping elastic piece 22 will be gradually toggled, so that the clamping elastic piece 22 can be inserted into the clamping block 23. After the clamping elastic piece 22 is inserted into the clamping block 23, it will bounce up and hook the clamping block 23. A blocking block 24 is fixedly connected to the side of the clamping block 23, a pull ring 25 penetrates through the inner side of the blocking block 24, a cavity 26 is opened in the inner side of the clamping block 23, a sealing glue is filled in the inner side of the cavity 26, a sealing strip 27 penetrates through the inner side of the clamping block 23, a sealing block 28 is fixedly connected to the inner side of the sealing strip 27 located in the cavity 26, a first pull rope 210 penetrates through the surface of the sealing block 28, and the first pull rope 210 drives the sealing block 28 to move through a pulling block 29. The sealing block 28 will pull up the sealing strip 27, so that the sealing glue in the cavity 26 enters the inner side of the clamping block 23 through the gap pulled up by the sealing strip 27, so that the clamping block 23 and the clamping elastic piece 22 are adhesively tightened. The first pull rope 210 penetrates through the clamping block 23 and is slidably connected. The first pull rope 210 penetrates through a pulling block 29, and the pulling block 29 is fixedly connected to the first pull rope 210. After the clamping elastic piece 22 is inserted into the clamping block 23, the pull ring 25 is pulled, so that the pull ring 25 pulls the first pull rope 210, so that the first pull rope 210 drives the sealing block 28 to move through the pulling block 29, and the sealing block 28 will pull up the sealing strip 27. One side of the pulling block 29 close to the sealing block 28 is fixedly connected to the surface of the sealing block 28.

A second pull rope 212 is fixedly connected to the inner side of the packaging bag body 1, and one end of the second pull rope 212 far away from the inner side of the packaging bag body 1 penetrates through the connecting strip 211 and is fixedly connected. A pulling groove 213 is opened on the surface of the scratch-proof plate 3, a pulling strip 214 is arranged inside the pulling groove 213, the pulling strip 214 is pulled, so that the pulling strip 214 tears off the connecting strip 211 through the second pull rope 212, and thus the gift can be taken out through the gap where the connecting strip 211 is torn off, which is convenient and fast. One end of the second pull rope 212 penetrating through the connecting strip 211 is fixedly connected to the surface of the pulling strip 214, and the pulling strip 214 is pulled, so that the pulling strip 214 tears off the connecting strip 211 through the second pull rope 212.

[0026] Based on the above embodiments, when the packaging bag is used for gift packaging, open the opening at the top of the packaging bag body 1. As the packaging bag body 1 is opened, the anti-scratch plate 3 will rotate around the bending groove 21, which can ensure that the opening of the packaging bag body 1 can be stably opened to the maximum state. Put the gift into the packaging bag body 1. After the gift packaging is completed, close the opening at the top of the packaging bag body 1 and push the symmetric anti-scratch plates 3 closer to each other, so that the clamping elastic piece 22 approaches the clamping block 23. When the clamping elastic piece 22 is gradually inserted into the clamping block 23, the inclined surface of the clamping elastic piece 22 will be gradually toggled, so that the clamping elastic piece 22 can be inserted into the clamping block 23. After the clamping elastic piece 22 is inserted into the clamping block 23, it will bounce up and hook the clamping block 23. If the packaging bag body 1 needs to be reused or transported for a short distance, do not pull the pull ring 25. If the transportation is bumpy or the packaging bag body 1 needs to be sealed, after the clamping elastic piece 22 is inserted into the clamping block 23, pull the pull ring 25, so that the pull ring 25 pulls the first pull rope 210, and the first pull rope 210 drives the sealing block 28 to move through the pulling block 29. The sealing block 28 will pull up the seal strip 27, so that the sealing glue in the cavity 26 enters the inner side of the clamping block 23 through the gap pulled up by the seal strip 27, making the clamping block 23 and the clamping elastic piece 22 adhered tightly, avoiding the packaging bag body 1 being opened due to transportation bumps.

[0027] The anti-scratch plate 3 fixedly connected to the outer surface of the packaging bag body 1 can reduce the probability of scratching and cutting when the packaging bag body 1 is transported. When taking the gift inside, the pull strip 214 can be pulled, so that the pull strip 214 tears off the connecting strip 211 through the second pull rope 212, and then the gift can be taken out through the gap where the connecting strip 211 is torn off, which is convenient and fast.
